16 Claims, 4 Drawing Figures 1 OVERHEAD GLUE POT APPARATUS BACKGROUND OF THE INVENTION Overhead glue pot apparatus that includes a pick up roll and a glue pan.

In the prior art it is old to provide a stringer or return roll which have bearings and seals located below the level of the glue in the glue pan. Additionally with such stringer or return roll there is usually provided fixed scrapers or doctor blades. In order to obviate the need i of such stringer or return roll and the usual accompany- SUMMARY OF THE INVENTION Overhead glue pot a'pparatusthat includes a pick up roll to pick up glue from a glue pan,-a metering roll for controlling the amount of glue on the pick up rollthat is available for transfer to a transfer roll of the machine with which the glue pot'apparatus is used,and a removable string trough for catching glue falling fromthe nip portions of pick up roll and transfer roll that does not fall into the pan.

One of the objects of this invention is to provide in overhead glue pot apparatus, a glue pan of'a new and novel configuration to facilitate cleaning the pan without disassembling said apparatus. Another object of this invention is to provide a new andnovel string trough that isremovably mounted adjacent the front wall of the glue pan for catching glue falling forwardly of the pan from the nip portionsof the glue pick up roll of overhanging glue pot apparatus and'the transfer roll of the machine with whichsaid apparatus is used. An additional object of this invention is to provide new and novel structure stationarily mounted for-stripping'off ating member on the container for releasably retaining the container on the bracket whereby the container can i be moved from a generally horizontal position to a'v'ertical condition while maintaining the discharge end of the spout of the container in overhanging relationship to the glue pan.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view of the apparatus of this invention, other than that parts are broken away, the glue supply-mechanism is shown in cross section, and the portion of the conveyor illustrated is shown much more closely adjacent the glue pan than it actually is;

I FIG. 2 is a horizontal view, part in cross section, generally taken along the line and in the direction of the arrows 22 of FIG. 1;

FIG. 3 is'a rear view, generally taken along the line and in the direction of the arrows,3-3 of FIG. 1, other than the gluecontainer is not shown; and

FIG. 4 is an enlarged, fragmentary vertical crosssectional view generally taken along the line and in the direction of arrows 4-4 of FIG. 2 to more clearly illustrate the string trough and the front part of the glue pot pan relative the glue pick up roll and the glue transfer roll.

Referring now to-the drawings, the overhanging glue pot apparatus of this invention includes a frame having a pair of side frame members 12 and 13 which dependingly mount the glue pan, generally designated 14, and

extend along either side thereof. The glue pan includes a pair of side walls 15, a rear wall 16, a bottom wall 17 and a front wall 18.

Rotatably mounted by the side frame members to extend downwardly into the pan to pick up the glue therefrom is a glue pick up roll 20 which is of conventional construction. A sprocket 21 is keyed to the glue roll shaft 22 for drivingly rotating said shaft and thereby the glue roll 20 which is mounted on said shaft. A suitable drive connection 24 is provided between gear 21 and the motor 25. Conventional s'crappers 23 are provided between the roll 20 and theside frame members.

Cutouts 26 are provided in the sidefra me members for mounting slide blocks 27 for limited horizontal movement, springs 28 on bolts 29 that are threaded into the side frame members resiliently urging the slide blocks in a forward direction toward the pick up roll. The slide blocks rotatably mount a shaft 30 which in turn mounts a metering roll 31 to rotate therewith. Throughthe aforementionedmounting of the metering roll, the springs 28 resiliently retain the metering roll in a selected spaced relationship to the pick up roll while at the sametime permitting the metering roll moving away therefrom to permit'lumps' of hardened glue and foreign matter to pass between said rolls.

A gear 35 is keyed tothe shaft30 to be drivenly rotated by gear mechanism 36, said gear mechanism in turn being driven by a gear 37 that is keyed to the shaft 22. The gear ratios are such that the metering roll rotates at a slower speed than the pick up roll.

Mounted by the side frame members at a lower elevation than the axis of rotation of the metering roll and slightly spaced from the exterior circumferential surface of the pick up roll isthe premeter bar 40. The purpose of providing the premeter bar is to strip off part of the excess of glue that is picked up by the pick up roll and thereby decrease the amount of glue that is elevated adjacent to the metering roll which is vertically above the premeter bar. and angularly spaced relative the metering. bar in the direction opposite the direction of rotation 71 of the pick up roll.

A handle 42 is mounted by mounting members 43 portion' thereof and extends diagonally such as shown in FIG. 2, there being provided a dowel aperture 50 through the horizontal leg that is spaced from slot 49.

The glue container, generally designated 54, has a container member 53, a cover SS'threaded thereon, the

cover having a central aperture through which the elongated spout 56 extends. The spout has an annular flange 56a within the cover that is secured to the cover by a screw 57 and a screw 58. The screw 58 has a dowel portion that extends outwardly beyond the cover for being extended into the dowel aperture when the container is mounted in a position of use with the flat circular surface seatedon the bracket 48. To be noted is that the spout is of a sufficient length to extend downwardly into the glue pan when the container is mounted on a bracket 48.

In moving the container into a mounted position on the bracket, the spout is merely layed along the edge of the glue pan to extend generally horizontally with the discharge end of the spout overhanging the interior of the pan and then the glue container is tilted upwardly with the discharge end of the spout extending right into the glue in the glue pan almost immediately. The spout slips through the slot 49 and the container is moved such that the screw dowel end moves into the dowel aperture 50 to prevent the glue container from accidentally falling off the bracket 48, while permitting the container being moved vertically to remove the container from the bracket.

Referring in particular to FIGS. 1 and 4;the glue pot tion 17a that extends from a location beneath the pick up roll to the end wall 16 and an areuately curved portion 17b having a radius of curvature eminating from the axis of rotation of the pick up lroll, portion 17b underlying the lower most portion of the pick up roll and having one edge integrally joined to the adjacent edge of portion 17a and an opposite edge integrally joined to the front wall 18. Portion 17!; extends to a substantially lower elevation directly beneath the lowermost part of the pick up roll than any other part of the bottom wall. The front wall is inclined upwardly and forwardly from portion 17b and has an upper edge almost directly beneath the nip formed by the pick up roll and the transfer roll 65 of the machine with which the apparatus of this invention is used. For example wall 18 may advantageously be inclined at about 60 for a pick up roll of about a diameter of about 4 /2 inches.

A string trough 66 has an upper portion 66a that underlies the wall 18, portion 66a having an upper edge almost directly beneath the aforementioned nip of rolls 20, 65. Further, the trough 66 has a bottom wall 66b that extends substantially forwardly of the aforemen tioned nip to be in underlying relationship to the rearward part of the transfer roll 65 of the machine with which the apparatus of this machine is used, the trough wall 66b from its front terminal edge being curved downwardly andthence upwardly to the location where its integrally joined with portion 66a. The lowermost part of portion 66b is at aboutthe same elevation as wall portion 17a. The front terminal edge of portion 66b is at a substantially higher elevation than the lowermost part thereof, at a substantially lower elevation than the top edge ofthe front wall and a substantial distanee forwardly of the front wall. The rear. portion of trough 66 is located between the side wall portions of the pan side walls that extend forwardly of the lower portion of the front wall. Through the provision of the trough 66', drops of glue falling from the location of transfer of glue from'roll 20 to roll 65 fall by gravity onto wall 66!) to be collected by trough 66. The trough pan bottom wall 17 has a generally flat horizontal por- 66' is of the same width as the front wall of the glue pan and is removably mounted on transverse frame member 70 by suitable latches or clips (not shown). Frame member 70 is mounted by the side frame member.

The apparatus of this invention is mounted on a machine wherein the work conveyed by the conveyor passes beneath the glue pan, the roll 65 being of a substantially larger diameter than roll 20 and extending to a substantially lower elevation than the bottom of the glue pan.

With the apparatus of this invention mounted on the machine with which it is to be used, and the sprocket 21 being driven in the direction ofarrow 71 and roll 65 being driven in the direction of arrow 72, the pick up roll elevates glue thereon up to adjacent the premeter bar 40 where excess glue carried by the roll that is of a thickness greater than the spacing of roll 20 and bar 40 is stripped off the roll 20 and falls back into the glue pan. The glue remaining on the roll 20 is next carried to adjacent the metering roll where the excessive thickness of glue is stripped off, the metering roll drive and the location of the metering roll being such that the metering roll revolves slowly enough that the major portion of the glue. which the meter roll strips off from the pick tip roll will run off from the lower portion of the metering roll and return to the glue pan by gravity. In this connection the surface of the metering roll is of a material that the glue has a minimum tendency to adhere to the metering roll and will run freely back down into the glue pan. The glue carried bythe pick up roll past the metering roll is carried to the transfer roll and transferred thereonto. Substantially all the glue that falls free of the pick up roll and the transfer roll at the nip thereof falls into either the glue pan or trough 66. Due to transfer roll extending to a substantially lower elevation than both pick up roll and the pan 14 to transfer glue onto an article on conveyor 85 that pass beneath the pan, the pan cannot extend far enough forwardly of the pick up roll to catch much of the glue that falls onto trough 66.

To be noted is that the front wall 18 is inclined at an angle and extends sufficiently forward of the lower portion of the pick up roll and wall portion 17b is curved such that the interior walls of the pan are accessible for cleaning with scrapers, brushes, water and steam jets without the necessity for disassembling the glue pan or pick up roll from the side frame members.
